Improvement in millstone dress



PATENT MANASSEH FRIES, OF PHILADELPHIA, y PENNSYLVANIA, ASSIGNOR vOEONE- HALF HIS RIGHT TO KREIDER, ZINDGRAF 85 OO., OF SAME PLACE.

IMPROVEMENT IN MILLSTONE DRESS.

Specification' forming part of Letters Patent No. 119,134, datedSeptember 19, 1871.

To all whom @t may concern:

Be it known that I, MANAssEH FRIEs, of the city and county ofPhiladelphia and State Of Pennsylvania, have invented an ImprovedMillstone Dress, of which the following is a specilication:

My invention consists in laying out the grind- Aing-face Of a millstonein bunches or gangs of number can be used. When the grain falls into theeye of the stone and is caught between the stones it is first onlycracked and a motion given to it. As it is driven around between thestones each gang of furrows a a in the runner is constantly crossing thecorresponding gangs of furrows of the bed-stone, the grain is shearedner, and its reductionis completed to particles of the required grade bypassing over the lands or iiouring surfaces.

The dressing' of the stones or the laying out in contiguous or adjacentgangs or bunches of furrows permits the use of a greater land orflouring surface, where the actual flouring is performed.

The advantages gained by my invention are mainly in the quantity andquality of the work done. In comparison with other millstone dresses,twice as much grain can be ground in a given time. The stones grindevener, liner, and livelier, and require less power, for the reason thatby my dress the stones have more iiouring surface, and more channels forthe meal to escape.

I claim as my invention- The millstone dress, consisting of the bunchesor gangs of adjacent furrows a, with the intervening land Or iiouringsurfaces b, when arranged with relation to each other, in the manner andfor the purpose shown and described.

In testimony whereof Ihereunto sign my name in presence of twosubscribing Witnesses.

Witnesses: MANASSEH FRIES.
